Instructions
Seat yourself comfortably on a solid chair, with your back straight and unsupported. Keep your feet planted about shoulder-width apart.
Elevate one arm out to the side and above your head with your bicep facing your ear and your fingertips extended over your head.
Gently lean away from the side on which your arm is elevated creating a stretch along the extended side of your body.
Lower your arm and straighten your torso to get back to the starting position.
